[QUOTE="joseph02, post: 15456905, member: 166909"] yea dustin & Darren5.0L I really didn't think about it and how I'm gonna do it exactly but just thinking about it I need to replace the alternator or modify its place, timing chain and cover. I can get a complete Navi heads with cams and valve cover for a good price. For the air intake I think doing a plate that can make the 2v lower intake fits with the heads. Not sure if this is an easy job to do especially that even if I use 1/4 inch thick plate it might change the flow or its speed due to friction, pressure and heat. also I do not think that I need to change the wiring harness I am already using 4.6l harness on 5.4l and its working great, I have the egr system delete and all its accessories. the exhaust I will use the stock manifold or any headers because I am sure that I will need to make a cut on the engine bay for cleaners for any headers I choose. Now with the 2v heads the stock manifold almost touches the wall. I am asking this becasue I am going to rebuild the engine and going to use a kit from jdm [url]http://www.teamjdm.com/jdm-5-4l-lightning-harley-engine-rebuild-kit/[/url] and not sure really which way to go with for not only higher numbers but for a good strong healthy pony power on the street :rockon: :burnout: for now I am pushing the engine to its limit and I dont want to wait to brake it & its Sad to lower the Boost :nono::nono: Any opinions will be appreciated :beer: [/QUOTE]
